Whenever I open a new tab, the new tab opens to a yahoo search page. It used to open to just a blank tab and changed somehow. I've been unsuccessful at changing it back.
Start Firefox in [[Safe Mode]] to check if one of the add-ons is causing the problem (switch to the DEFAULT theme: Tools > Add-ons > Themes).
* Don't make any changes on the Safe mode start window.
See:
* [[Troubleshooting extensions and themes]]
* [[Troubleshooting plugins]]
If it does work in Safe-mode then disable all extensions and then try to find which is causing it by enabling one at a time until the problem reappears.
* Use "Disable all add-ons" on the [[Safe mode]] start window to disable all extensions.
* Close and restart Firefox after each change via "File > Exit" (Mac: "Firefox > Quit"; Linux: "File > Quit") -
How can I change the homepage that displays when I open Firefox?
I just had to reinstall a program that had become corrupted, and somehow the process changed my Firefox homepage. Not only is the new one not what I want, when I try to open Firefox I get a notification from WOT that the new page is unsafe.
I do one open Firefox window. I would like to use it to change my default homepage back to the one I had, but I can't find how to do that.https://support.mozilla.org/en-US/kb/How%20to%20set%20the%20home%20page

In the end i'm getting 15 Bitmaps in localImages.
localImages is Bitmap[]
The method get a Bitmap and the Bitmap pixel format is: Format8bppIndexed
I want that in the end the 15 Bitmaps in localImages will be also pixel format of Format8bppIndexed.
The problem is that if i change everywhere in the method from: PixelFormat.Format32bppArgb to PixelFormat.Format8bppIndexed
I'm getting exception on the line:
pArray[a + b * bmDataArray.Width] = color2.ToArgb();

Line 469 is: pArray[a + b * bmDataArray.Width] = color2.ToArgb();Thorsten Hi,
Too complicated for me i will try to look on it.
Also if you will have time later maybe you could look at it too ?
For now what i tried was to get the returned 15 new Bitmaps to a local array:
bitmaps = ImagesComparison.get_images_with_clouds(b1);
for (int i = 0; i < bitmaps.Length; i++)
ConvertTo1or8Bit.ColorToGrayscale(bitmaps[i]);
break;
Then make a convertion with a new class trying to convert the Bitmaps to 8 bit in the memory without saving them first to the hard disk. This is the new class:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Drawing.Imaging;
using System.Drawing;
using System.IO;
namespace mws
class ConvertTo1or8Bit
public ConvertTo1or8Bit()
public static Bitmap ColorToGrayscale(Bitmap bmp)
int w = bmp.Width,
h = bmp.Height,
r, ic, oc, bmpStride, outputStride, bytesPerPixel;
PixelFormat pfIn = bmp.PixelFormat;
ColorPalette palette;
Bitmap output;
BitmapData bmpData, outputData;
//Create the new bitmap
output = new Bitmap(w, h, PixelFormat.Format8bppIndexed);
//Build a grayscale color Palette
palette = output.Palette;
for (int i = 0; i < 256; i++)
Color tmp = Color.FromArgb(255, i, i, i);
palette.Entries[i] = Color.FromArgb(255, i, i, i);
output.Palette = palette;
//No need to convert formats if already in 8 bit
if (pfIn == PixelFormat.Format8bppIndexed)
output = (Bitmap)bmp.Clone();
//Make sure the palette is a grayscale palette and not some other
//8-bit indexed palette
output.Palette = palette;
return output;
//Get the number of bytes per pixel
switch (pfIn)
case PixelFormat.Format24bppRgb: bytesPerPixel = 3; break;
case PixelFormat.Format32bppArgb: bytesPerPixel = 4; break;
case PixelFormat.Format32bppRgb: bytesPerPixel = 4; break;
default: throw new InvalidOperationException("Image format not supported");
//Lock the images
bmpData = bmp.LockBits(new Rectangle(0, 0, w, h), ImageLockMode.ReadOnly,
pfIn);
outputData = output.LockBits(new Rectangle(0, 0, w, h), ImageLockMode.WriteOnly,
PixelFormat.Format8bppIndexed);
bmpStride = bmpData.Stride;
outputStride = outputData.Stride;
//Traverse each pixel of the image
unsafe
byte* bmpPtr = (byte*)bmpData.Scan0.ToPointer(),
outputPtr = (byte*)outputData.Scan0.ToPointer();
if (bytesPerPixel == 3)
//Convert the pixel to it's luminance using the formula:
// L = .299*R + .587*G + .114*B
//Note that ic is the input column and oc is the output column
for (r = 0; r < h; r++)
for (ic = oc = 0; oc < w; ic += 3, ++oc)
outputPtr[r * outputStride + oc] = (byte)(int)
(0.299f * bmpPtr[r * bmpStride + ic] +
0.587f * bmpPtr[r * bmpStride + ic + 1] +
0.114f * bmpPtr[r * bmpStride + ic + 2]);
else //bytesPerPixel == 4
//Convert the pixel to it's luminance using the formula:
// L = alpha * (.299*R + .587*G + .114*B)
//Note that ic is the input column and oc is the output column
for (r = 0; r < h; r++)
for (ic = oc = 0; oc < w; ic += 4, ++oc)
outputPtr[r * outputStride + oc] = (byte)(int)
((bmpPtr[r * bmpStride + ic] / 255.0f) *
(0.299f * bmpPtr[r * bmpStride + ic + 1] +
0.587f * bmpPtr[r * bmpStride + ic + 2] +
0.114f * bmpPtr[r * bmpStride + ic + 3]));
//Unlock the images
bmp.UnlockBits(bmpData);
output.UnlockBits(outputData);
return output;
But they are still 32 bit. So i guess i didn't realy understand yet how to do it. -

How do I change the default text for when I open up pages?
How do I change the default text for when I open up pages?
Colin,
You may substitute any text you like for the "Placeholder Text", as it is called, in Pages. Click on the existing placeholder text and type something more to your liking. Do this in as many places as your particular template of interest demands. Then, Format > Advanced > Define as Placeholder Text. Lastly, File > Save as Template.
Now that you have defined a Custom Template to your liking, you can go to Pages Preferences and under the General tab's first section, define the new custom template as your default for each new document.

How do you change the drive that my Iphone backs-up to on my computer? My first attempt to back-up and i received a pop-up stating that I do not have sufficient memory/space, knowing that I have over 120GB of free space...any ideas? thanks
dave0915,
iTunes stores your iPhone backups in the Library folder in your Home folder.
iTunes places the backup files in these places:
Mac: ~/Library/Application Support/MobileSync/Backup/

I changed the password used to access my gmail account. Thunderbird is still using the old password to access the account. How do I change the password that Thunderbird is using. The last time this happened I ended up creating a new Thunderbird account for gmail. Creating the new Thunderbird account at least let me enter the new password. I really don't want to have three Thunderbird accounts for the same gmail account.
Please do not respond with suggestions about using Password Manager. I do not use it and do not intend to start. I looked and none of my Thunderbird passwords are displayed there. All I want to do is change the password in Thunderbird. If Thunderbird does not have a feature allowing you to change it's passwords, one should be added.This is the only way.

How do I change the auto ID prompt when the window pops up for my password when I try to install App updates? I've changed my ID but the old ID is embedded in the password prompt and I can't work out where to change it. So I'm unable to install any of my App updates.
Did you go to Settings>Store>Apple ID? Tap the old ID and sign out. Sign in with your new ID. If you changed the name associated with the ID this should work If you created an entirely new ID, you have to use the old ID and password to update the apps since they will always be tied to that ID and password,
